Abstract

To improve throughput while reducing wasteful use of resources at a time of packet retransmission. To achieve this object, a new-part acquiring unit (104) acquires a part of a block generated by a block generating unit (101), as a new part to be contained in a packet. A retransmission-part acquiring unit (105) acquires a part of a block corresponding to a NAK as a retransmission part to be contained in a packet among blocks held in a retransmission buffer unit (102). An encoding unit (106) groups a new part acquired by the new-part acquiring unit (104) and a retransmission part acquired by the retransmission-part acquiring unit (105), and generates a packet. A modulating unit (107) modulates a packet output from the encoding unit (106). A wireless processing unit (108) performs a predetermined wireless transmission process to a modulated packet, and transmits a processed modulated packet via an antenna.
